Embodiment 1

[0122] [Example 1: Mixture of 1233zd(Z) and 3-methylpentane]

[0123] Put the mixed solution (400g) of 1233zd(Z) and 3-methylpentane into an Othmer type gas-liquid equilibrium distillation device, and use a gas chromatograph to obtain the gas phase composition and liquid phase when the equilibrium state is reached. composition. The measurement results are shown in Table 1 and figure 1 .

[0124] [Table 1]

[0125]

[0126] From table 1 and figure 1 It can be seen that the mixed solution of 1233zd(Z) and 3-methylpentane contains 99.9999 mass % to 80.0000 mass % of 1233zd (Z) and 0.0001 mass % to 20.0000 mass % of 3-methylpentane relative to the total amount of the mixed solution. In the case of methylpentane, (like) azeotropic compositions are formed. Among them, when 99.9999 mass% to 90.0000 mass% of 1233zd(Z) and 0.0001 mass% to 10.0000 mass% of 3-methylpentane are contained with respect to the total amount of the mixed solution, the fluctuation of the liquid composit...

Embodiment 2

[0127] [Example 2: Mixture of 1233zd(Z) and 2,3-dimethylbutane]

[0128] Except having used 2,3-dimethylbutane instead of 3-methylpentane, in the same manner as in Example 1, the gas phase composition and liquid phase composition at the time of equilibrium state were calculated|required using the gas chromatograph.

[0129] The measurement results are shown in Table 2 and figure 2 .

[0130] [Table 2]

[0131]

[0132] From Table 2 and figure 2 As shown, the mixed solution of 1233zd(Z) and 2,3-dimethylbutane contains 99.9999 mass% to 75.0000 mass% of 1233zd(Z) and 0.0001 mass% to 25.0000 mass% of the total amount of the mixed solution When 2,3-dimethylbutane is used, an (like) azeotropic composition is formed. Among them, when 99.9999 mass % to 85.0000 mass % of 1233zd (Z) and 0.0001 mass % to 15.0000 mass % of 2,3-dimethylbutane are contained with respect to the total amount of the mixed solution, the fluctuation of the liquid composition becomes more Small and theref...

Embodiment 3

[0133] [Example 3: Mixed solution of 1233zd (Z) and industrial hexane]

[0134] Except for using industrial hexane instead of 3-methylpentane, in the same manner as in Example 1, the gas phase composition and the liquid phase composition in an equilibrium state were determined using a gas chromatograph. The measurement results are shown in Table 3. As an example of industrial hexane used, it contains 2,2-dimethylbutane (2,2-DMB), 2,3-dimethylbutane (2,3-DMB), 2- A mixture of hexane isomers of methylpentane (2-MP), 3-methylpentane (3-MP), n-hexane (n-Hex), methylcyclopentane (MCP), the mixture The composition (mass ratio) was 2,2-DMB / 2,3-DMB / 2-MP / 3-MP / n-Hex / MCP=5.7 / 5.5 / 5.8 / 5.8 / 64.3 / 12.6.

[0135] [table 3]

[0136]

[0137] As can be seen from Table 3, the mixed solution of 1233zd (Z) and industrial hexane contains 99.9999 mass % to 85.0000 mass % of 1233zd (Z) and 0.0001 mass % to 15.0000 mass % of industrial hexane relative to the total amount of the mixed solution. Wi...

Abstract

The present invention provides a solvent composition containing a novel (class) azeotropic composition containing Z-1-chloro-3, 3, 3-trifluoropropene (HCFO-1233zd (Z)), which is mild to the environment, and a hexane isomer, the composition of which does not change even if volatilized. Also provided are an aerosol composition containing the solvent composition, a cleaning agent, and a method for cleaning an article using the cleaning agent. An azeotrope-like composition according to one embodiment of the present invention contains Z-1-chloro-3, 3, 3-trifluoropropene and at least one substance selected from the group consisting of 3-methylpentane, 2, 3-dimethylbutane, 2, 2-dimethylbutane, and methylcyclopentane.

Description

technical field [0001] One embodiment of the present invention relates to a solvent composition comprising a (like) azeotrope composition containing Z-1-chloro-3,3,3-trifluoropropene With more than one isomer of hexane. In addition, one embodiment of the present invention relates to an aerosol composition containing the solvent composition, a cleaning agent, a method for cleaning articles using the cleaning agent, a composition for forming a coating film, and an article with a coating film. Manufacturing methods, dehydrating agents, flushing agents, and lubricant solutions. Background technique [0002] Fluorine-containing saturated compounds such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are used in foaming agents, heat transfer media, solvents, cleaning agents, and the like. In these applications, it is particularly preferred to use single-component or (like) azeotrope compositions, ie components that do not substantially fractionate when boiling...
